Serology Les. 1 Pt. 2 Mod 1

These flashcards cover key vocabulary and concepts related to immunity and vaccination outlined in the lecture notes.

Cellular Immunity

The immune response that is mediated by T lymphocytes, which are responsible for attacking infected cells directly.

Humoral Immunity

The immune response that is mediated by B lymphocytes, which produce antibodies to neutralize pathogens.

Innate Immunity

The natural immunity we are born with, which serves as the first line of defense against pathogens.

Neutrophils

A type of white blood cell crucial for fighting infections, especially during the initial immune response.

Complement

A group of proteins that enhance the ability of antibodies to clear pathogens from an organism.

Cytokine Storm

An excessive and uncontrolled release of pro-inflammatory cytokines, often leading to harmful effects during infection.

Acquired Immunity

The immunity that develops over time as a result of exposure to antigens or vaccination.

Anamnestic Response

The secondary immune response where the body rapidly produces antibodies due to previous exposure to an antigen.

Active Immunity

Immunity that results from the immune response to an infection or introduction of a vaccine.

Passive Immunity

Temporary immunity gained by receiving pre-formed antibodies, such as through maternal antibodies or immunoglobulin injections.

Allergen

A substance that can cause an allergic reaction, acting as an antigen in these cases.

Anaphylaxis

A severe, potentially life-threatening allergic reaction that can occur rapidly after exposure to an allergen.

Booster Shot

An additional dose of a vaccine given to enhance or restore the immune response.

Immunocompromised

A state in which the immune system's ability to fight infectious diseases is reduced or absent.

Antigen

A substance that induces an immune response, typically by being recognized by antibodies.
